BELT GUIDE.

Specification of Letters Patent.

Patented Oct. 12, 1909.

Application filed November lS, 1908. Serial No. 463,181.

To all whom it may concern: I

Be it known that I, GARRET H. TENPAS, a; citizen of the United States, and a resident; of the town of Sherman, in the county of. Chautauqua and State of New York, have: invented a new and Improved Belt-Gruide, of which the following is a full, clear, and; exact description.

My invention relates to belt guides, myv more particular purpose being to provide an efiicient form of belt guide for use in connection with portable engines and including. means whereby, in a few minutes of time,- various adjustments'may be made relative to the position occupied by the moving belt.

Reference is to be had to the accompany ing drawings forming a part of thisspecification, in which similar characters of reference indicate corresponding parts in all-v the figures.

Figure 1. is a perspective showing my im-- proved belt guide in use; Fig. 2 is an en-= larged fragmentary plan view, partly broken away and in section, of the spindle for carry-1 ing the guiding pulley, this view also show-Z I ing some of the mountings for said spindle;

8, 9, 10. A bolt 11 extends into a collar 13;

and against a supporting rod 14, which sustains a cylindrical head 16, these parts being integral. Another bolt 15 extends through the bracket 7 and from the back side, that is, through any one of the holes 8, 9, 10, and holds the collar 13.

A stationary shaft 17, having generally the form of a solid cylinder is extended into the head 16 which has generally the form of a hollow cylinder for the purpose of receiving it. A bolt 18 extends into the head 16 for the purpose of engaging the stationary shaft 17 and holding the latter rigid in relation to the supporting rod 14. Bolts 19, 20 engage the head 16 and for this purpose extend through the brackets 21, 22 which are provided with slots 23, 24, to accommodate the bolts. The purpose of the bolts 19, 20 is to hold the brackets 21, 22 tightly against the head 16 while the belt is running, so as to maintain the shaft 17 exactly in a predeand bolts 33 termined position, and to prevent the shaft from swaying. The slots 23, 24 allow shift ing of the bolts 19, 20 to permit the adjustment of the head 16, and once adjusted the head remains rigid. The holes 8, S), 10 in the bracket 7 are for the purpose of raising or lowering the belt guide as a whole, thus accommodating my device, when once constructed, to any size or type of engine.

The brackets 21, 22 are held in position by aid of bolts 25, 25 which engage the lower portions of the supporting plate and the running board 6. Brackets 26, 27 are provided with bearings 28, 29 which engage the shaft 17. A guide pulley 30 is provided with flanges 31 and is revolubly supported upon the shaft 17. An idle roller is shown at 32 and is mounted upon a stationary shaft 34 by aid of set collars 33 The idle roller 32 extends a little distance intermediate the flanges 31 carried by the guide pulleys 30', as indicated in Fig. 3. This arrangement eifectively prevents the belt 39 from traveling edgewise beyond certain limits. One end of the shaft 34 is pivotally mounted upon a bolt 35 supported by a head 35 which is integral with the bracket 26. The bracket 27 is provided with a slot 36 which serves as a bearing for the other end of the shaft 34, and said end of the shaft is held stationary by means of a hand wheel '39 having astem 40 entering the head of the bearing 27 and engaging the shaft 34. y

The main pulley of the engine is shown at 37 and is keyed upon a revoluble shaft 38. A belt 39 engages this pulley and is in operative relation to the same. At 40 is an oil cup which by aid of a pipe 41 is connected with the bearing 29, the latter having a conical oil space 42 into which the oil gravitates from the cup 40 so as to lubricate the pulley 30 and the portion of the shaft 17 upon which said pulley runs.

The operation of my device is as follows: The parts, except the belt, being arranged as above described, the engineer brings the belt into engagement with the pulley 37 and secures the belt between the rollers 32, 30. This holds the belt, and the engine is now backed up so that the belt is tightened. The engine being in operation, the belt turns the pulley 30 constantly, the flanges 31 preventmg the belt from moving sidewise to any great extent relatively to the pulley 37. If a strong wind be blowing against the belt drive' pulley, no matter if the size or type.

of the engine may be considerably different; from the one shown in the accompanying drawings. In some engines, the drive pulley is farther away from the boiler than in other engines, and notwithstanding this fact, ray-belt guide can be adjusted to practically any engine,

Having; thus described my invention, I; claim as new and desireto secure by Let-. 'ters Patent In a belt guide, the combination ofa; roller provided withflanges, a second roller, disposedparallel to said first-mentioned roller and extending intermediate said flanges so as to confine abelt between said rollers, connectionsfrom one ofsaid rollers,

to theother for-supporting one of-said rollers, and means for supporting the other of saijd rollers.

2 In a beit guide, the combination of a normally stationary shaft adapted to be, shifted bodily sons to alter the general positi'on of the axis of a rotation thereof, a pulley. mounted upon said shaftand loose relatively thereto, brackets secured upon said shaft and extending laterally therefrom, a

seeondshaft mounted upon said brackets and 3, I-OlleI"1I101-1Il;ted' upon said second shaftfor-the; purpose of -en-gagi-ng a belt disposed intermediate said rollers.

3;. Th'ecombination of a normally fi-xed shaft, brackets mounted upon said shaft and extending laterally therefrom, a roller revolubly mounted upon said shaft intermediate said brackets, said roller being provided with flanges, another shaft journaled upon said bracket s, and a guide roller mounted upon said shaft, and extending intermediate said ,SlOtS, a sleeve encircling said shaft and engaged by said bolts for the purpose of steadying said shaft, brackets mounted upon said shaft, a roller mounted upon said shaft and disposed intermediate said last mentioned brackets, an idle roller revolubly supportedby said last-mentioned brackets, and a belt disposed intermediate said first-mentioned roller and said idle roller.

5. The combination ofa stationary bracket to be mounted upon a boiler or the like, said stationary bracket being provided with a plurality of holes, a collar to be mounted upon said. bracket, a bolt for extending through any one of said holes chosen at will and engaging said collar for the purpose of supporting the latter in different positions, a shaft mounted upon said collar and extending outwardly from said bracket, aguide pulleyjourna-led upon said shaft and adapted to engage a belt, and brackets for bracing said shaft-in order to render the same steady.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
